4 Claims. (Cl. 53-29 My invention relates to a method of opening and filling flat tubular coin Wrappers.

Expanded cylindrical tubular coin wrappers are in general use and are easy to fill with coins. The disadvantage of'this type of coin wrappers is that they take up too much space in shipment or storage.

Tubular coin wrapers are also made flat or collapsed, and the advantage is that a great deal of space is saved in shipment and storage. However, it is very difficult to expand a fiat or collapsed tubular coin wrapper into a true cylindrical shape for properly receiving the coins.

I provide a device for use in the practice of the method. This device includes a rigid body portion having a cylindrical recess, and a slightly tapered recess leading into the discharge end of the cylindrical recess. The body portion has an outer recess which has a high degree of taper and leads into the discharge end of the slightly tapered portion or recess. A flat or collapsed tubular coin wrapper is manually operated to radially compress the same to partly open it sufliciently so that its end maybe introduced into the outer highly tapered portion, and by manipulation of the wrapper, it is completely expanded and will become truly cylindrical when its free end reaches the cylindrical recess. This will render the quick and convenient insertion of the coins into the expanded originally flat tubular wrapper.

Figure 6 is an end elevation of the same,

Figure 7 is a view similar to Figure 1 showing the next and final step of the method,

Figure 8 is an end elevation of the same,

Figure 9 is a central vertical longitudinal section through a device used in the practice of the method,

Figure 10 is an enlarged vertical section through the tubular tapered member, indicating the degree of taper of the slightly tapered recess.

In the drawings, the numeral 10 designates a rigid body portion, which may be formed of plastics or any suitable material. This body portion 10 includes a flange 11, at its top. The body portion 10 is arranged in an upstanding position, in use, and is held stationary upon a suitable supporting frame, not shown. r

The body portion 10 has a cylindrical recess 12 which is vertically inclined to correspond to the inclination of the body portion 10. The cylindrical recess 12 has its discharge end leading into a slightly tapered recess 13, increasing in diameter downwardly. The recess 13 is circular in cross section and its upper reduced end terminates at the shoulder 14. The taper of the recess 13 is slight and is preferably at 2 to 3 with respect to the central longitudinal axis of the recess 12. The recess 13 is concentric with the recess 12. The body portion 10 is provided with a highly tapered recess 15,-1eading into the lower end of the recess 13. The recess 15 is circular in cross section and is concentric with the recesses12 and 13.

The numeral 16 designates a slide or valve'which is held in a closed position by a spring 17. The slide 16 has a coin opening 18, and when theslide 16 is shifted to the open position, opening 18 will register with recess 12, and coins from the holder v or hopper, not shown, will pass into and through the cylindrical recess 12. I

The numeral 19 designates an originally flat or collapsed coin wrapperjwhich is tubular and formed of paper or the like. The numeralZO designates the coins.

In the practice of the method, the tubular coin wrapper 19 in its collapsed condition, has its intake end brought" into contact with the lower end of the body portion 10, Figures 1 and 2. The collapsed coin wrapper is arranged radially of the recess 15, and the edges of the coin wrapper are slightly pressed inwardly by the fingers and the coin wrapper is partly expanded, Figures 3 and 4, and the expanding is gradually increased as the partly expanded wrapper is forced upwardly into the sharply tapered recess 15, Figures 3 and 4. The partly expanded wrapper 19 is now moved upwardly further and enters the lower end of the slightly tapered recess 13, and the expanding of the partly expanded wrapper 'at its upper end gradually continues to circumferentially expand, and is approaching the cylindrical shape. When the upper end of the wrapper 19 reaches the shoulder 14, the wrapper 19 will be truly cylindrical. While the partly expanded wrapperis having its upper end inserted into the recesses 15 and 13, the wrapper may be turnedslowly upon its longitudinal axis, thus ironing the-wrapper so that its intake end will be truly cylindrical when it contacts with the shoulder 14. The shoulder 14 is slightly wider than the thickness of the wall of the wrapper 19, so that the inner face of the wrapper will be substantially flush withthe inner face of the recess 12, and will not extend beyond the inner face of the recess 12. I

After the wrapper has been inserted into the recess13 and its upper end contacts with the shoulder 14, the finger may be inserted into the -lower. end of the wrapper, Fig

ure 9. It is essential thatthe intake end or portion of the wrapper be held cylindrical, and that thewrapper be held at least partly expanded throughout its entire length, during the filling process. However, the wrapper need not be expanded to a truly cylindrical form throughout its entire length, before the coins are introduced therein.

When the wrapper has its upper end expanded to the truly cylindrical form, Figure 9, and the wrapper is held in the position shown in Figure 9, the valve 16 is shifted to the open position and the coins will drop through the opening 18 into the cylindrical recess 12, and drop into the wrapper 19. The action of these coins, by gravity, completes the expanding of the wrapper throughout its entire length, and the stack of coins are illustrated in Figure 9. The finger may remain in the lower end of the wrapper 19 and the wrapper separated from the body portion 10, at which time, the ends of the wrapper are folded over the stack of coins, and the method is complete.

The interior diameter or" the tapered recess 13, at its reduced end, is the same as the exterior diameter of the completely expanded tubular coin wrapper 19. Therecess 13 is slightly tapered, as stated, and the taper of this recess is from 2 to 3 with respect to the central vertical longitudinal axis of the recess 12 or with respect to a line 16' parallel with the axis 15'. If this taper were too abrupt, the action of the tapered recess would roll or fold the free end of the tubular wrapper 19, which does not '7 occur with the slight taper.
